President Donald Trump announced a slew of tariff-related updates yesterday. The changes come as most countries will face rates of 15% to 20% beginning overnight, at 12:01 am ET.
Trump yesterday said India will face 25% tariffs and an added penalty for purchasing Russian oil. Brazil will face 50% tariffs next week; Trump separately announced 50% tariffs on all copper imports. The US will also end the global de minimis exemption later this month, which allowed packages valued below $800 to enter duty-free.
Some countries negotiated lower tariffs in the lead-up to tonight’s deadline. South Korea negotiated a baseline of 15% in exchange for investing hundreds of billions of dollars in the US. Indonesia, Japan, the Philippines, the UK, Vietnam, and the European Union also reached revised deals. Pakistan is expected to finalize a deal shortly.
The average effective tariff rate is estimated to rise to 18.4%, the highest level since 1933. Clothing and shoes will be especially affected, with prices predicted to rise roughly 40% in the short term. Learn more about tariffs via 1440 Topics here.

Hearings began yesterday in the federal probe into January’s fatal midair collision of an American Airlines jet and an Army Black Hawk in Washington, DC. Sixty-seven people were killed in the plane crash—the US' deadliest since November 2001.
The National Transportation Safety Board opened hearings with an animation showing the aircrafts' flight path before they crashed over Reagan National Airport (watch here, warning—sensitive). The Black Hawk’s barometric altimeter, built in the 1970s, misread the helicopter’s altitude by 80 to 100 feet, ultimately flying above the 200 feet altitude limit. Army pilots reportedly also missed air traffic control instructions to pass behind the jet.
A March investigation flagged concerns over small separation distances between helicopters and planes in Reagan’s airspace, citing 85 near misses between October 2021 and December 2024. Documents revealed yesterday indicated air traffic controllers had sought to change the helicopter route, but ultimately abandoned the effort.

World's Deepest Ecosystem
|
Chinese researchers have identified fields of underwater creatures nearly 6 miles below sea level, the deepest complex ecosystem ever discovered, a study published yesterday in Nature reveals. Listen to an interview with the researchers here.
The ecosystem spans over 1,500 miles across the Kuril-Kamchatka and Aleutian trenches—depressions in the Pacific Ocean seafloor between Russia and Alaska. Through 23 dives in a three-person submersible, researchers found fields of brightly colored marine tube worms, mollusks, and clams (see more, w/video).
With no access to sunlight, the organisms appear to rely on liquid methane and hydrogen sulfide for energy in a process known as chemosynthesis (see how it was discovered). Researchers think the methane comes from microbes in the seafloor—and that these ecosystems may be more widespread than previously thought.
Explore a visualization of deep-sea inhabitants here.

The Salty Science Behind Optimal Hydration
|
|
It’s easy to forget our sweat isn’t just water—it’s loaded with minerals like sodium, potassium and magnesium that our bodies need to function at their best. These electrolytes aren’t just nice to have, they’re essential for maintaining hydration, supporting muscle and nerve function, and optimizing energy production in our cells. Let those levels dip, and you’ll feel it: fatigue, brain fog, sluggish workouts.
That’s where LMNT comes in. Created by former research biochemist Robb Wolf, LMNT is a zero-sugar electrolyte drink mix and sparkling drink with enough sodium, potassium, and magnesium to help you feel and perform your best—without the sugar, artificial colors, or other dodgy ingredients found in other sports drinks.
